STK1000 have a combined MMC and SD card connector.
MMC and SD memory cards are used to connect secondary storage to products. Secondary storage can be used to store operating systems and it can be used to store data such as music or movies. Hand held GPS devices may use the memory card to store maps or tourist guides.
The SD and MMC connector on STK1000 lets you create and test such applications in the lab before you make your own product. The MMCI interface from the AVR32 device on the daughter board is designed specifically for interfacing SD and MMC memory card.
The MMC/SD memory card connector is located under the RGB LEDs.
Bidirectional data lines DAT[0..3] and CMD line have 47 KOHM pull-up resistors to 3.3V
Two switches are included in the connector. These are:
Refer the help files of the daughter board to find out what interfaces are used and which peripheral on the processor are connected to the interface.
